SAN D-INJECTOR FOR LOCOMOTIVES.

SPECIFICATION forming part of Letters Patent No. 557,725, dated April'7, 1896. Application filed October 19, 1898. Renewed December '7, 1895.Serial No. 571,443. (No model.)

To all 20. 2.0711 it may concern.-

Be it known that I, HUGO TIRMANN, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Sand-Injectors forLocomotives, of which the following, with the accompanying drawings, isa specification.

The annexed drawings and the following description set forth in detailone mechanical form embodying the invention, such detail constructionbeing but one of various mechanical forms in which the principle of theinven tion may be used.

In said annexed drawings, Figure I represents a side elevation of myimproved sandinjector for locomotives; Fig. II, an axial section of thesame; Fig. III, a transverse section on the line III III in Fig. II;Fig. IV, a transverse section on the lines IV IV in Fig. II 5 Fig. V, aperspective detail view of the hooded diaphragm or valve-seat; Fig. VI,a face view of the discharge side of said diaphragm or valve-seat, andFig. VII a face view of the valve.

A'casing A is formed with the general outline of a pipe-elbow and has aneck a, by means'of which it is attached to and connects with thesand-box of the locomotive, and a neck a, to which is attached the upperend of a Y-coupling B, to the branches of which the sand-pipes for thedrive-wheels at that side of the locomotive are attached The neck a andthe upper end of the Y-coupling are each formed with a verticalpartition, respectively, a and Z),'which thus divide the neck and thecoupling to distribute the sand which passes through the casing toeither of the sand-pipes.

At the junction between the horizontal and vertical portion of thecasing is secured a diaphragm or valve-seat C. Said diaphragm has anopening a in its upper portion and an opening 0 in its lower portion. Acurved hood 0 overhangs the upper opening of the diaphragm at thereceiving side of the same. A

partition 0 extends vertically from the receiving side of the diaphragmtoward the inner face of the hood, and said partition is extended in awing a the lower edge of which follows the curve of the casing and whichwing extends above the lower edge of the hood. The receiving end of thecasing is thus longitudinally and vertically divided by the partitionhaving the wing, said partition corresponding in its position in thecasing with the partitions in the neck a and the Y-coupling.

A valve-disk D has a seat against the discharge-face of the diaphragm,and said valvedisk is formed at its upper portion with an opening (Z,which may be brought to register with the opening 0 or c in thediaphragm by rotating the valve-disk upon its center. The valve has acentral stem (7, to the outer end of which is secured a stem (Z of acontrollinghandle D. The stem passes through a detachable screw-cap Aupon the end of the casing. A sleeve 6 fits upon the stem of the valveand has two diametrically opposite wings e, which may register with thepartition of the diaphragm. A head E is secured upon said sleeve and mayrotate within the horizontal portion of the casing, so that the sleeve,wings, and head may rotate with the valve when the latter is rotated bymeans of the controlling-handle. A spring F is coiled around thecontrolling-stem (Z and bears against the head and the screw-cap,thereby forcing the valve to a seat upon the diaphragm Air-pipes g aresuitably connected to an airpump or other source of compressed air, andsaid air-pipes enter the sides of the casing and are provided withnozzles g which proj ect into the spaces between thedlood and thediaphragm, one on each side of the partition, and points downward.Screw-plugs a are preferably inserted through the sides of the casing atpoints opposite the nozzles, so that they may receive all the wearcaused by the air-blast and consequent movement of the sand and may berenewed whenever worn out. Neeedle-valves g are provided to regulate theair-blasts passing through the nozzles. Air-pipes g pass from thecouplings Got the air-pipes through the sides of the casing and one downthrough each of the branches of the Y-coupling, so that any'clogging ofsand in the branches of the coupling maybe removed by air-blasts throughsaid pipes.

An air-nozzle H extends through the sides of the vertical portion of thecasing opposite the hood and has a pipe connection 71- to the air-pipecoupling G, and said nozzle is controlled by a valve h, so thatair-blast may be admitted against the convex face of the hood to clearaway any sand which may have accumulated upon the hood.

By means of the herein-described device sand may be applied at eitherone or more drive-wheels of a locomotive and may be applied in smallquantities by means of the airjets or in large quantities by allowingthe sand to directly run through the device. By turnin g the valve theopening in the same may be brought to register with the upper or loweropenings in the diaphragm or to register with the openings at one sideor the other of the vertical partitions. Air-blast to the nozzles may besuitably controlled by valves upon the air-pipes. If the sand-pipesshould for some reason or other become clogged, air-jets maybe admittedinto them by the branch airpipes g and sand which accumulates upon thehood may be blown away by an air-blast from the end nozzle H.

Other modes of applying the principle of my invention may be employedfor the mode herein explained. Change may therefore be made as regardsthe mechanism thus disclosed, provided the principles of constructionset forth, respectively, in the following claims are employed.

I therefore particularly point out and distinctly claim as myinvention 1. In a track-sanding device, the combination of a casingprovided with an inlet constructed to communicate with the sand-box andwith an outlet having two branches constructed to communicate withsand-pipes, Vertieal and longitudinal partition in said casing dividingthe latter into two longitudinal chambers each communicating with asand-pipe branch, a diaphragm in the casing transverse to the partitionand formed with an opening and a valve against said diaphragm formedwith an opening and constructed to form or close passage through thediaphragm at either or both sides of the partition, substantially as setforth.

2. In a track-sanding device, the combinaiion of a casing provided withan inlet constructed to communicate with the sand-box and with an outlethaving two branches constructed to communicate with sand-pipes, verticaland longitudinal partition in said casing dividing the latter into twolongitudinal chambers each communicating with a sand-pipe branch, adiaphragm in the casing transverse to the partition and formed with anopening, air-blast device constructed to raise the sand in the inletportion of the casing, and a valve against said diaphragm formed with anopening and constructed to alternately form or close passage through thediaphragm at either or both sides of the partition, substantially as setforth.

3 In a track-sanding device, the combination of a casing provided withan inlet communicating with the sand-box and an outlet having twobranches communicating with sand-pipes, vertical and longitudinalpartition in said casing dividing the latter into two longitudinalchambers each communicating with a sand-pipe branch, a diaphragm in thecasing transverse to the partition. and formed with openings in itsupper and lower portions, air-blast device constructed to raise the sandin the inlet portion of the casing, and a valve against said diaphragmand formed with an opening and constructed to be turned so as to bringits opening to register with the openings in the diaphragm,substantially as set forth.

4. In a traeksanding device, the combination of a casing provided withan inlet communicating with the sand-box and an outlet communicatingwith the sand-pipes, a diaphragm located within said casing and providedwith a hood and a vertical partition toward the inlet, a rotatablevalve, and a head provided with wings, substantially as set forth.

5. In a track-sanding device, the combination of a easin g having aninlet and an outlet, a stationary valve-seat having a hood and avertical partition toward the inlet, a rotatable valve, a head formedwith wings, and an airnozzle beneath the hood, substantially as setforth.

6. In a track-sanding device, the combination with a casing having aninlet communieating with the sand-box and an outlet communicating withthe sand-pipes, and mechanism within said easing for controlling thepassage of sand through said casing, of air-nozzles entering said casingto provide air-jets to loosen the sand in the same, and pipes connectedto said air-nozzles and extending through said easing into the upperportions of the sand-pipes, substantially as set forth.

7. In a track-sanding device, the combination of a casing having aninlet communicating with the sand-box and an outlet communieating withthe sand-pipe, a transverse diaphragm in said casing having an openingin its upper portion and an overhanging hood toward the inlet, anair-nozzle beneath said hood, and an air-nozzle directed toward the sideof the hood which faces the sand-inlet, substantially as set forth.

8. In a track-sanding device, the combination of a casing containing thesand and having an outlet for the same, an air-jet nozzle entering saidcasing, and a wear-plug inserted at a point directly opposite theair-jet nozzle, substantially as set forth.

In testimony whereof I afiix my in presence of two witnesses, this May,1893.
